KES CT images of specific lung ventilation (\({\rm{s}}\dot{V}\)), in one representative control rabbit (A); lung morphology (B) and \({\rm{s}}\dot{V}\) images in a MCH-challenged animal at baseline (C) and during the challenge (D). Note the constriction of central conducting airways and small peripheral ventilation inhomogeneities during MCH infusion.
